REGISTER COMPANY, OF CHICAGO, ILLINOIS mncmmsm FOB mums oon'rmuous To all whom it may coawem;

Be it known that I, WALTER R. BARKER, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in a Mechanism for Feeding Continuous Paper Strips to Typewriters, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to make and use the same.

My present invention relates to typewriter machines and means for feeding paper in a strip or strips to the carriage and platen thereof where the same may be written upon and then the desired length of paper severed from the strip or strips. More particularly, my present invention relates to feeding a continuous strip of paper that has been previously folded back and forth longitudinally and rolled upon a spool or core and whic is sheared or cut at the folded edges prior to the entry of the sheared strips into the carriage of the typewriter. Y

In paper feed mechanisms, in which a plurality of sheets or continuous strips are fed in superposed relation, it frequent] occurs that the strips, one or more of t em will slip longitudinally or transversely an get out of alinement so that the forms which are printed upon the respective strlps will not be in registry, and consequently when matter is typewritten upon the original or outer strip) it will not appear in thecorresponding ank spaces upon the manifolded copies. I have found that b providing a wide strip of paper and fol ing the same back and forth upon itself longitudinally, the forms will be maintained in registry with each other more readily than where the strips are fed from separate rolls. In the mechanism of this character, it is desirable, however, to shear the paper at the folded edges just prior to their-entry into the carriage in order to receive the manifolding material. This will permit the printed forms to be discharged from the t ewriter in separate super sed strips, an the operator nee do after one form has been completed is to tear the strip laterally at the lower edge of each printed form so that duplicate, triplicate or an 4 number of manifold copies may thus be 0 tained.

()ne of the objects of my present invention resides in providing effective means for renmmors, nssreivoa "r0 Application filed January 25, 1 924. Seriatlto. 688,460.

I prefer to carry out the several objects of my invention in substantially the manner hereinafter fully described, and asmore particularly pointed out in the claims, reference being made to the accompanying drawings thlzlrt hform a part of this specification, in w 1c Figure l is ,a vertical slde elevation of the upper portion of a typewriter machine showing the application of my invention thereto.

Mounted upon the carria e in.

front of the platen is a paper shiel or and comprises a main guard E against which the discharged por- U0 ets, bills-of-lading, etc.

. the upright arms K so tend above the latter,

paper strips will rest after leav- Pivotally mounted upon is a pair of arms G thattains the paper against the latter. The pins 11a F which support the arms of this cutter bar project from T-shaped brackets J m'ounted at the opposite ends of the carriage and exand said brackets each have upwardly extended rearwardly inclined arms K.

' Extending horizontally between said arms K is a rod 10 over which the folded paper strips are adapted to be' fed and which is guided by means of adjustable stops 11 that may be moved longitudinally upon the rod to space them apart approximately the width of the strip or folded sheet being fed into the machine. A guide plate 12 is mounted upon and depends from the rod 10, the upper end 13 of said plate being bent over rearwardly to provide a lock that is engaged with the rod in the manner shown in dotted lines in Figure 1. This plate 12 extends downwardly towards the platen and terminates a short distance therefrom, and the paper is maintained against the same by means of a presser device, which latter consists of friction rollers 14 mounted intermediate the ends of a horizontal rod 15 that of the extensions 16 having loops or eyes at their upper ends that surround the rod 10 at the upper ends of the arms K and permit a' pivotal movement of the structure. Intermediate their ends the extensions 16 are bentgobliquely as seen in Figure 1 so that their lower portions are disposed substantially vertical, this being done for the purpose of clearing the cutter blades'which project from the arms K toward the paper.

As seenin Figure 5, the paper is referably an elongated sheet that is folde longitudinally back and forth uponfl'itself, and the same is printed with suitable forms and notations such as are used in the "'sales tick- The pa or, after being printed and folded, is role upon the suitable spool or folded "in a pack and the end is placed over therod 10 between the guide blocks 11 and then extends down over the plate 12, past the cutters and into the carriage between the platen and the. feed rollers d. The cutters comprise twosets of parallel blades 17 mounted at their ends in holders 18'secured to the ends of irregularly shaped brackets 19 that extend out from v that the blades extend onto the late 12 from each side thereof and space from the plate so that the blades extend obliquely beyond the folded b of the carriage and are:

is connected by means insane edges of the paper strip. The blades have their cutting edges faced upward and towards the edges of the paper so that when the paper is moved downwardly by the paper feed mechanism and platen the folded portions will be engaged with the knife edge of the blades and be severed so asto provide a plurality of separated strips of paper of the desired width of the sale ticket or bill-of-lading and having printed thereon the desired form; Thus it will be seen the sheet is maintained in its folded condition until immediately before it reaches the feed mechanism of the typewriter so that the forms printed onthe sheet. will be kept in registry until the separate tickets are cutter bar H. a

In combination with a typewriting machine havin .a longitudinally reciprocable carriage and a platen rotatable therein, a frame secured to and supported solely by said carriage, a supporting late upon said frame and inclined upwardly away from said platen, a paper web folded longituditorn off along the nally back and forth upon itself and movable over said plate, obllquely dis 'osed cutters supported b said frame. a ove said plate and engage said web while the flatter'iis; being moved upon saidplate wherebyto slit said web into separate strips that are receivedand fed by the platen and meansbetween the cutter and platen for maintaining the paper in contact with said plate.- I

3.

having its lower portion urged towards the plate to engage the web between the cutters and the platen.

4. In combination with a typewriting machine having a longitudinally reciprocal carriage and a platen rotatable thereon, a frame supported by and movable with said carriage, a supportin plate upon said frame and inclined upwar ly from adjacent said platen, a paper web folded longitudinally back and forth upon itself and movable over said plate,adjustable guides upon said frame between which the paper passes, obliquely disposed cutters supported by said frame above said plate and engaged with the folded edges of said web while the latter is being moved upon saidplate whereby to slit said web into separate strips that are received and.fed by said platen, and a member pivotally mounted upon said frame and having its lower portion urged towards the plate to engage the web between the cutters and the platen.
